  • Artificial Intelligence Facilitates Tissue Substructure Identification from Spatial Resolved Transcriptomics

    A research team led by Prof. ZHANG Shihua from the Academy of Mathematics and Systems Science has proposed a new computational tool, STAGATE, to decipher tissue substructures from spatial resolved transcriptomics. The model uses artificial intelligence technology to integrate spatial location information and gene expression profile of spatial spots. In this algorithm, a graph attention autoencoder is introduced, with a graph attention mechanism in the middle hidden layer, which can learn the heterogeneous similarities between neighboring spots adaptively.

  • Researchers Extend Quantum Amplification to Floquet Systems

    Researchers from University of Science and Technology of China have realized quantum amplification in a Floquet system based on xenon noble gas. The Floquet system can extend the operation bandwith of quantum amplification, and can enhance several signals simultaneously. This result has wide applications in the research of fundamental physics.

  • Direct Oxidative Transfer Process Contributes to Water Purification

    Researchers developed a new water decontamination technology, the direct oxidative transfer process (DOTP). In DOPT, a direct redox reaction between pollutants and oxidants occurred on the catalyst surface. Products formed were stabilized and spontaneously underwent surface polymerization or coupling reaction. As a result, products accumulated on the catalyst surface, contributing to the effective elimination of aquatic pollutants.
